Natural history of very severe aortic stenosis

We sought to assess the outcome of asymptomatic patients with very severe aortic stenosis.

A history of frequent dental care reduces the risk of tooth loss but not periodontitis in older subjects

OBJECTIVES: Information on the significance of dental care in older adults is limited. We hypothesized that regular dental visits has an effect on the number of remaining teeth and periodontal conditions in older subjects. MATERIALS AND METHODS: 1020 randomly selected individuals age 60 - 96 from the Swedish National Study on Aging and Care Blekinge received a comprehensive oral health examination. RESULTS: Dentate women and men had, on average 18.4 teeth (SD +7.6,) and 18.9 teeth (SD + 7.5) respectively (NS). In the youngest group (60 and 66 years old) with less than one dental visit per year, 37% had >20 teeth, compared with 73% among those with at least annual visits. Among the old-old, comparable figures were 1.8 % and 37% respectively. Across age groups, bleeding on probing was 23 %.When adjusting for age, and number of teeth GLM univariate analysis failed to demonstrate an effect of dental visit frequency on alveolar bone loss (p = 0.18), the number of periapical lesions (p = 0.65), or the number of endodontically treated teeth ( p = 0.41). Frequent dental visitors had more teeth than infrequent visitors (p = 0.001). CONCLUSIONS: Tooth loss and alveolar bone loss severity increase with age. Individuals with regular dental visits retained more teeth but the frequency of dental visits had no impact on plaque deposits, gingival inflammation, or alveolar bone levels.

Liberation as Revolutionary Praxis: Rethinking Buddhism Materialism

While it is only in recent decades that scholars have begun to reconsider and problematize Buddhist conceptions of “freedom” and “agency,” the thought traditions of Asian Buddhism have for many centuries struggled with questions related to the issue of “liberation”—along with its fundamental ontological, epistemological and ethical implications. With the development of Marxist thought in the mid to late nineteenth century, a new paradigm for thinking about freedom in relation to history, identity and social change found its way to Asia, and confronted traditional religious interpretations of freedom as well as competing Western ones. In the past century, several attempts have been made—in India, southeast Asia, China and Japan—to bring together Marxist and Buddhist worldviews, with only moderate success (both at the level of theory and practice). This paper analyzes both the possibilities and problems of a “Buddhist materialism” constructed along Marxian lines, by focusing in particular on Buddhist and Marxist conceptions of “liberation.” By utilizing the theoretical work of Japanese “radical Buddhist” Seno’o Girō, I argue that the root of the tension lies with conceptions of selfhood and agency—but that, contrary to expectations, a strong case can be made for convergence between Buddhist and Marxian perspectives on these issues, as both traditions ultimately seek a resolution of existential determination in response to alienation. Along the way, I discuss the work of Marx, Engels, Gramsci, Lukàcs, Sartre, and Richard Rorty in relation to aspects of traditional (particularly East Asian Mahāyāna) Buddhist thought.
